Implementing two nearly similar methods

I need to implement a class with two similar methods, which are overloaded:

class MyClass {        
  public:              
    int myMethod(int a) {  
      // Logic here
    }
    int myMethod(int b, int c) {  
      // Logic here
    }
};

I want to reuse code and code is very similar for both, I am thinking about creating some generic method and just choose between them in implementation.

class MyClass {        
  public:    
    int myMethod(int a) {  
      myGenericMethod(a, 0, 0);
    }
    int myMethod(int b, int c) {  
      myGenericMethod(0, b, c);
    }
  private:
    int myGenericMethod(int a, int b, int c) {
      // Full logic is here
    }   
};

But I am still wondering if this solution is ok. Maybe there is a more elegant solution?
